Section 2 (1-2) Convection Currents and the Mantle

Vocabulary


heat transfer- movement of energy from an warmer object to a cooler object.-three types are radiation, conduction, and convention.
radiation- energy transfer through empty space.
conduction - heat transfer by movement of a heated fluid
convection- heat transfer by direct contact of matter.
density- how much mass there is in a volume of substance.
convection current- flow which transfers heat within a fluid.
